The cumulative explanation for evolution is so strong that at this point, if a 100 million-year-old bunny fossil were found, a more reasonable explanation for its existence than evolution being wrong would be time travel. We don't have any physics that says it's impossible, but the proverbial pre-Cambrian bunny alone is incapable of disproving evolution, IMHO.
